Water level gauge series
1 Overview
1.1 This series of instruments is designed and manufactured according to the national standard GB/T11828.1-2002.
1.2 the instrument is a single floating ball type water level gauge. When the water level meter works, there is only one cable in the inclined shaft, which affects the floating ball, tracks the change of water level, and realizes the automatic measurement of the water level.
1.3 this type of instrument is suitable for the inclined shaft angle (the angle between the horizontal axis and the earth line in deviated wells) in the range of 90 DEG -25 DEG, bore diameter is not less than 160 ~ 250mm, the maximum effective length (between the highest water level and low water level of the slope length) use range of 80m in place, and inclined axis must be straight well, the wall must be smooth and convex obstacles.
1.4 the water level encoder of the instrument displays the stroke of the floating ball in the inclined shaft, and the vertical amplitude of the water surface should be collected by computer, and the output value of the encoder and the inclination angle of the inclined shaft should be calculated according to the formula.
1.5 this type of instrument is widely used in water level measurement of reservoirs and lakes. The construction of inclined shafts in reservoirs and lakes can save a lot of investment compared with the construction of large shafts.
2 main technical parameters
2.1 float stroke (L): 0 - 80m,
Vertical variation of water level (H): H = L * Sin alpha
The 2.2 level encoder resolution: 1 cm
2.3 measurement accuracy (when the angle value when there is no error less than 0.2%).
2.4 floating ball diameter: 130mm, 200mm optional
2.5 output signals: 13bit gray (RS485 or 4-20mA interface matching)
2.6 transmission distance (using standard cable): 150m
2.7 environmental temperature: -10 ~ 85 C
Relative humidity; < 90% (40 C)
2.8 weight: 26.5Kg
